v150919-RC: Cache Statistics placeholder when no stats available

[raamdev]

When installing ZenCache Pro on a site that does not have any prior Cache Stats history available, the Cache Stats page shows an empty area where the pie chart would normally be. It would be nice if this area was filled in with an example image of the pie chart, greyed out, with some text on it that says something like, "Cache Stats history not available, please check back later."

Next Actions

• See this line of JavaScript where the $chartA div is hidden when there are no stats.

• Same thing here for Chart B (i.e., chart on the right side).

• Modify one or both of these, so that instead of hiding the chart, you fill it with an <img /> tag.

  $chartA.html('<img src="..." />');
  // $chartA.hide();

• Compress menu-pages.js into menu-pages.min.js

• Submit PR.

Generating the URL which leads to the image:

• After this line of code add the following.

  'emptyStatsImageUrl' => $self->url('/src/client-s/images/empty-stats.png'),

• In JavaScript, you can access it like this:

  $chartA.html('<img src="' + plugin.escHtml(plugin.vars.emptyStatsImageUrl) + '" />');

Same thing here for Chart B (i.e., chart on the right side).

So there should be two empty-stats placeholder images?

[jaswrks]

Ideally, yes. However, you might decide that just doing $chartA is enough to convey what you need to.

Compress menu-pages.js into menu-pages.min.js

Note that when you run the compress-js script I sent you, you can exclude the --old-style arg, as ZenCache Pro is up-to-date and uses .min.js (new) instead of -min.js (old).
